  • The inward and outward electric file for a closed surface in units of <img alt="\mathrm{\mathrm{N}-\mathrm{m}^2 / \mathrm{c}}" src="https://entrancecorner.oncodecogs.com/gif.latex?%5Cmathrm%7B%5Cma

The inward and outward electric file for a closed surface in units of \mathrm{\mathrm{N}-\mathrm{m}^2 / \mathrm{c}} are respectively \mathrm{8 \times 10^3 and 4 \times 10^3} . Then the total charge inside the surface is -

Option: 1

\mathrm{4 \times 10^3 \mathrm{c}}


Option: 2

\mathrm{-4 \times 10^3 \mathrm{C}}


Option: 3

\mathrm{\frac{-4 \times 10^3}{\epsilon} c}


Option: 4

\mathrm{-4 \times 10^3 6 c}

\mathrm{\phi=\frac{Q_2}{t_0}}
\mathrm{Q=\phi \epsilon_0}  ___________[1] 
\mathrm{\phi=\epsilon_0\left[-8 \times 10^3+4 \times 10^3\right]}
\mathrm{\phi=-4 \times 10^3 \epsilon_0}
